Name: Rhus glabra - Rhus trilobata Central Rocky Mountain Montane-Foothill Shrubland Alliance
Reference: NatureServe Biotics 2019
Description: The vegetation is characterized by a sparse to moderately dense shrub layer dominated by <i>Rhus glabra</i> or <i>Rhus trilobata</i>. The sparse to moderately dense herbaceous layer is composed of <i>Aristida purpurea var. longiseta, Festuca idahoensis, Pseudoroegneria spicata</i>, and other graminoids or forbs. This shrubland alliance is found in the lower montane and foothill regions around the Columbia Basin, including river canyons, and extends north and east into the Central Rockies and to the foothills and breaks in the western Great Plains. Stands occur on a variety of sites, including steep lower slopes in canyons and valley bottoms where gravel and boulder colluvium accumulates, near talus slopes as garlands, at the heads of dry drainages, and toeslopes in the moist shrub-steppe zones. Stands also occur in patches or strips along the shoulder slopes of river breaks. Soils are often shallow and rocky.
